A minor memoir, which is not to minimize its indigenous interest both personal & anthropological. Lamb, a forest engineer, has told Manuel Córdova-Rios' story, apparently just as it was told to him, with irreducible candor. The latter is now 83 with 50 grandchildren but as a boy of 15 he was captured & taken to live (in the buff except for a piece of string) with the Huni Kui Indians at the headwaters of four rivers in the Amazon. He was a chosen person of this tribe whose name signifies Chosen People, fed on breast of partridge & indoctrinated as a once & future chieftain via a green liquid (honi) which induced vision sessions. Thereby he not only experienced "mental acceleration" but also a power to anticipate the future (he foresaw his mother's death). He also shared in all their rituals of death, marriage, birth, the hunt etc. of this apparently hard-working & vigorous people before he finally escaped some years later.--Kirkus
